Beit known that I, CHARLES H. TREAT, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan, haveinvented certain new and useful Improvements in Ventilating Apparatus,of which the following is a specification, reference being had thereinto the accompanying drawings.

The invention relates to an apparatus for Ventilating factories orsimilar places where in the course of manufacture obnoxious vapors andgases are necessarily developed and the invention consists in thepeculiar construction ofthe Ventilating means, as will be more fullyhereinafter set forth.

In the drawings illustrating my invention I have shown the apparatus asapplied to a building designed and equipped for the manufacture of coke,the ventilating means being adapted in this instance to free thebuilding from the gases arising from the bituminous coal when sprayed inthe usual manner to check combustion after it attains the condition ofcoke.

In the drawings, Figure 1 is a view in front elevation of the apparatus.Fig. 2 is an enlarged sectional view. Fig. 3 is an enlarged view, infront elevation, of a portion of the draft-conduit, the hood, and thetraveling receptacle; and Fig. 4 is a section taken on line :c of Fig 2looking in the direction of the arrows.

The reference-letter Arepresents a number of retorts or coking-ovensarranged in the usual manner in gas-houses in a number of verticalseries, as B, above a suitable flooring C. Beneath this flooring andconnected thereto and extending longitudinally of the series of retortsis an air-conduit D, having means, in this instance in the form of a fanE, for inducing a draft through the conduit to carry away the obnoxiousvapors and gases. I have here shown the air-conduit as communicatingwith the fan-casing lF and continuing to and through the side of thebuilding, as shown in Fig. l, so that the vapors will be dischargedoutside of the building. Any means may be employed,vhowever, forinducing a draft, and, if convenient, the fan and its casing may bedispensed with and theI air-conduit connected directly to the stack,which will produce the necessary amount of draft.

' preferably employed forcontrolling these openings.

J represents a hood having an open top K, forming an exit-opening,mounted in this instance beneath the draft-conduit for longitudinaltravel. Preferably the hood has traveling connections with the conduititself, the parts being so arranged that the hood may be moved asdesired beneath any of the several inlet-openings I-I and in operativerelation to the corresponding chute G. The means for permitting thelongitudinal travel of the hood comprises a track L, mounted uponcross-pieces M, attached to the draft-conduit, a corresponding invertedtrack O, secured to the lower face of the conduit to one side of theinlet-openings, a double hanger P upon the hood, the grooved rollers Qof which engage the track L, and similar wheels or rollerszR upon theopposite side of the hood, two in number and bolted directly to thehood, as shown in Fig. 2, to engage the track O. The hood is furtherprovided with an opening S in its side to admit the contents from thechutes G and is further provided at opposite sides of the opening withthe guard-plates T and U to guide the contents from the chutes Withinthe hood.

V represents a receptacle, preferably in the form of a car, mounted upontracks WV for longitudinal travel beneath the air-conduit and hood. Thehood, as shown, is provided with the depending portions or sides a andl) so proportioned as to project over the side edges of the car, whilethe ends c of the hood are cut away to allow the car to pass beneath thehood and into operative relation therewith.

The dampers controlling the inlet-openings in the draft-conduit areprovided with means for positively actuating the same independently. Thepreferable operating mechanism is a series of levers d, connected, as ate, to the dampers, which are pivoted in the conduit midway of theiredges, The greater portion of these levers, as shown, are within Y theair-conduit and proj ect outwardly there- IOS from, terminating inhandles f and having adjoining the conduit, and a movable hood formed intheir outwardly-projecting portions notches g, adapted to engage thewall of the air-conduit to lock the dampers in their open or closedpositions.

In the operation of the Ventilating mechanism when it is desired todischarge the contents of any of the retorts the car is moved on itstrack beneath the discharge-chute for the vertical series of retorts ofwhich the contents are to be withdrawn. The traveling hood is then movedover the car in operative relation with the chute, and the dampercontrolling the inlet in the draft-conduit opposite said chute isopened, the remaining dampers of the series being normally closed. Asthe coke is discharged through the hood into the car the operator spraysthe same in the usual manner to prevent further combustion of the coke,and the gases and vapors thus generated rise upwardly, passing throughthe exit in the hood into the draft-conduit through the dampercontrolled opening II. The draft induced through the conduit either bythe fan or stack, as previously set forth, carries the gases and vaporsoutside of the building, and thus properly ventilates the same.

While a special form of the apparatus has been shown, attention isdirected to the fact that various modifications may be made Without inany manner departing from the spirit of my invention, and I do not,therefore, Wish to be limited to the exact construction illustrated. Asa sample of a slight modification Where the proper draft is provided thedampers controlling the inlet-openings in the draft-conduit may beentirely dispensed with, the draft being of suflicient strength toprevent the gases from discharging into the building. The hood alsounder certain conditions may be dispensed with, in which instance thecar or other receptacle would be placed more directly beneath'theinlet-openings in the conduit. The detachment of the hood may be readilyeffected by reason of its peculiar and simple connections with theconduit.

What I claim as my invention isl. In a Ventilating apparatus, thecombination with a member having discharge-op enings longitudinallythereof, of a draft-conduit having a series of separated inlet-openingsextending longitudinally thereof in line with said discharge-openings, aseries of dampers controlling the inlet-openings, means forindependently operating the dampers, a traveling receptacle movable inoperative relation with any one of said conduit-openings and itscorresponding discharge-opening, and a hood for the receptacle havingopenings, one for iilling the receptacle from the chute and the otherfor communicating with the inlet-openm s.

g2. In a Ventilating apparatus, the combination with a draft-conduitprovided with a damper-controlled inlet-opening, of a chute adapted tofit overV a receptacle to be filled from the chute, the hood having anopening to register with the chute and another affording communicationwith the conduit through said inlet.

3. In a Ventilating apparatus, the combination with a draft-conduitprovided with an inlet-opening, of a chute adjoining the conduit, anopen-bottom hood having an auxiliary opening in its side registeringwith the end of said chute to admit the chute contents and an open topregistering with the inletopening in the conduit, and a receptaclearranged below the open bottom of the hood.

4. In a Ventilating apparatus, the combination with a member havingdischarge-openings, of an air-conduit provided with a correspondingseries of inlet openings, means for inducing a draft through saidconduit, and a hood mounted for travel longitudinally of thedischarge-openings and conduit and having an exit-opening adapted to bebrought in registration with any of the inlets in said conduit.
